Construction Calculators

Board Foot Calculator Construction Calculate board-foot volume and optional cost for milled lumber, or compare three named log-rule estimates in a separate mode. Concrete Block Calculator Construction Estimate CMU block count, mortar bags, sand, grout fill, and vertical reinforcement from wall dimensions, openings, block size, and waste allowance. Concrete Calculator Construction Estimate net concrete volume, an order quantity with visible overage, and whole premix bags for common pour shapes. Concrete Mix Calculator Construction Scale a published 1:2:4 nominal-mix material schedule, or scale custom dry parts from a known cement volume. Deck Board Spacing Calculator Construction Fit boards across a clear deck field, solve one even gap, or preserve the entered product gap with equal-width edge-board rips. Decking Calculator Construction Estimate whole deck boards, lineal decking, and fasteners for a straight rectangular deck with every gap and allowance shown. Drywall Calculator Construction Estimate whole drywall panels, covered area, joint tape, compound, and Type W screw weight from room dimensions or a known surface area. Floor Joist Calculator Construction Estimate field-joist count, joists to buy, optional rim-board length, and total lineal feet without pretending to size the structure. Flooring Calculator Construction Calculate planned packaged flooring, whole packages, leftover coverage, and optional material cost for one or more rooms. Framing Calculator Construction Count wall studs and plate boards from wall length and chosen on-center spacing, with rough-opening and purchasing details kept optional. Linear Feet Calculator Construction Convert a surface area to the running length of fixed-width material, with raw length kept separate from an optional order allowance. Lumber Calculator Construction Turn a known same-size board count into whole boards to buy, board feet, lineal feet, and optional cost. Lumber Weight Calculator Construction Estimate solid-lumber weight from actual dimensions or board feet, species density, quantity, and moisture content. Plywood Calculator Construction Estimate whole plywood sheets for a measured surface, or reverse sheets on hand into usable coverage. Plywood Weight Calculator Construction Estimate per-sheet and stack weight from dimensions, thickness, and a named current industry-average density or custom density. Rebar Calculator Construction Turn engineer-specified dimensions, cover, spacing, and bar size into bar counts, total length, theoretical stock-length equivalents, and approximate weight. Tile Calculator Construction Calculate tileable area, individual tiles, whole boxes, leftover coverage, and optional material cost for one or more surfaces.
